Deep Core

"Sorry, Artoo, but I've never jumped into the Deep Core before. It's crowded in there and things move fast and this isn't a well-established route yet, so I think an abundance of caution is warranted."

The Deep Core, sometimes referred to as the Core of the Galaxy, was a brightly lit region of the galaxy that lay at its very heart. A densely packed mass of stars and planets, the Deep Core was dangerous to navigate and largely left alone by galactic explorers.[1] At its center existed an ancient, supermassive black hole that bound the galaxy together.[2] Travelling towards the Core was referred to as going "coreward."[3]

In the game Star Wars: Jedi Challenges, the Deep Core is referred to as the Core of the Galaxy. The game describes it as a mysterious place in the center of the galaxy, where a challenge awaited for those who ventured there.
